Answer: Hypertonic, Hypotonic, Colloid
Explanation:
Osmosis is a process whereby a solvent moves through a cell membrane from a solution of lower concentration to a solution of higher concentration.
Hypertonic solution has more solutes than the bloodstream this causes solutes, it moves from intracellular fluid to extracellular fluid when a hypertonic solution is used.
A hypotonic solution has a lower solute concentration than the bloodstream, and this causes fluid to move from extracellular spaces into the cells, causing cells to swell.
Oncontic pressure is the opposite force that pulls fluid colloids such as albumin to move into the capillaries. When hydrostatic pressure is greater, fluid will leave the capillaries, when onctoic pressure is greater fluid will enter the capillaries.
No fluid shift is observed in an isotonic solution, because an isotonic solution, has the same solute concentration as blood, meaning an isotonic IV solution is equal in concentration to the blood and hence no fluid shift.
Answer:
B. DNA unzips before step 1.
Explanation:
This question is describing the process of gene expression, which is made up of two major stages namely; transcription and translation. Transcription is the process by which mRNA is synthesized from a DNA template while translation is the process where protein (amino acid sequence) is produced using the mRNA transcript.
This stages of gene expression has been summarized in the steps listed by Shura. However, prior to the formation of an mRNA molecule in step 1, the double stranded DNA has to unwind i.e. separate into single strands as initiated by the enzyme RNA polymerase. Therefore, the list should read as follows:
- DNA unzips
- A strand of RNA is made.
- RNA leaves the nucleus.
- RNA moves to the ribosome.
- A protein is made.
Answer:
Light
Explanation:
Light travels through empty space at 186,000 miles per second. The electricity which flows through the wires in your homes and appliances travels much slower: only about 1/100 th the speed of light.
